Abstract Physical injuries and psychological disorders following a road traffic accident (RTAs) are a serious public health problem. The objective of this work was to conduct a systematic review and update of studies on the prevalence and predictive variables of post-traumatic stress disorder (PTSD) after RTAs. A systematic search was performed in databases including Medline, PsycINFO, Scopus and Elsevier, of articles published between January 2015 and August 2019, following PRISMA guidelines. Initial search showed a total of 1062 articles, and 28 met inclusion criteria. The available literature is heterogeneous in regards to aims and methodology. Prevalence rates ranged from 2,39 % to 62%. The most robust predictors of PTSD include: female gender, perceived threat to life, lack of social support, persistent physical problems and previous emotional problems. The importance of early detection to prevent psychological sequelae is highlighted.

Abstract The DSM-5 presents an alternative dimensional model for personality disorders, which includes pathological traits organized in five major areas: Detachment, Negative affectivity, Psychoticism, Antagonism and Disinhibition. To evaluate this model, the Personality Inventory for DSM-5 (PID-5) was developed. However, it is unknown how the PID-5 would work adapted to our context. On the other hand, the PID-5 suffers from various limitations (e.g., not all facets are represented in the brief version, affecting the construct validity). The objective of this paper was to study the psychometric properties of an adapted version of the PID-5 to the Argentine population. We worked with a non-probabilistic sample of 393 subjects from the general population. The adapted version of the Personality Inventory for DSM-5 was administered together with the Adjectives Checklist to Assess the Big Five Personality Factors (AEP), a measure of the five traits of Big Five Model, normal equivalents of the pathological traits of the alternative model. The following data analyzes were performed: a) Exploratory Factor Analysis to evaluate the internal structure of PID-5; b) reliability analysis to assess the internal consistency of the different scales of the PID-5; c) item analysis to assess discriminating power; d) bivariate correlation analysis to analyze the relationship between PID-5 scores and the AEP; e) multivariate analysis of covariance (MANCOVA) to analyze significant differences due to gender, age, and possible interaction effects. Results indicated satisfactory psychometric properties. The Argentinean version of the PID-5 showed a five-factor structure similar to the original, with adequate levels of internal consistency and good discrimination indices. Regarding gender, men scored higher in Antagonism, Psychoticism and Detachment, and the effect size was significant although weak. On the other hand, women scored higher in negative affectivity, but the differences were not significant. Regarding age, young people presented higher scores than adults at all scales except in Detachment, and the effect size was significant although weak. Finally, significant relationships were found with the five factors of the big five model (e.g., strong and positive correlation between Negative Affectivity and Neuroticism; moderate and negative correlations between Detachment and Extraversion, and between Disinhibition and Conscientiousness). Additionally, other high correlations were found (e.g., between Agreeableness and Detachment; Conscientiousness and Psychoticism; Neuroticism and Disinhibition). These results are in line with those found in previous studies. Finally, moderate correlations were found between PID-5 scales (e.g., Disinhibition and Antagonism; Negative Affectivity and Disinhibition; Psychoticism and Disinhibition; and Detachment and Negative Affectivity). These correlations would imply the existence of some higher order factor that would cover the dimensions of the model. Although the results found are acceptable, this study has some limitations. First, we worked with general population, and in future work it would be important to administer the instrument in clinical samples. Second, the Antagonism scale was left with only 4 items, which may affect the construct validity of the instrument. In this regard, it would be convenient to add new items, not only on this scale, to obtain a final version with an intermediate length between 25 and 220 items of the two versions of the original scale. A version of approximately 60 items may be a good solution, that includes both the different facets of the model as well as time constraints if the instrument is pretended to be used within a diagnostic battery. Beyond these limitations, the present study provides preliminary evidence of validity and reliability for the adapted version of the PID 5, and could be a start point for its deepening and improvement to be implemented in clinical and research tasks.

Resumen El DSM-5 presenta un modelo dimensional alternativo para los trastornos de personalidad, que incluye rasgos patológicos organizados en cinco grandes áreas: Desapego, Afectividad Negativa, Psicoticismo, Antagonismo y Desinhibición. Para evaluar dicho modelo, se desarrolló el Personality Inventory for DSM-5. El objetivo de este trabajo fue estudiar las propiedades psicométricas de una versión adaptada del instrumento a población argentina. Se trabajó con una muestra no probabilística de 393 sujetos de población general. Se administró la versión adaptada del Personality Inventory for DSM-5 junto con el Listado de Adjetivos para Evaluar Personalidad, una medida de los cinco rasgos del modelo de los Grandes Factores de Personalidad (Amabilidad, Responsabilidad, Extraversión, Neuroticismo y Apertura a la experiencia), equivalentes normales de los rasgos patológicos del modelo alternativo. Los resultados mostraron propiedades psicométricas satisfactorias. La versión argentina del Inventario mostró una estructura de cinco factores similar a la original, con niveles adecuados de consistencia interna e ítems con buenos índices de discriminación. Se observaron diferencias por género y edad. Los hombres puntuaron más alto en Antagonismo, Psicoticismo y Desapego, y las mujeres en Afectividad Negativa. Los jóvenes puntuaron más alto en todas las escalas salvo en Desapego. Por último, se encontraron correlaciones significativas con los cinco factores correspondientes del modelo de los “cinco grandes” (ej., entre Afectividad Negativa y Neuroticismo). Los resultados brindan evidencia preliminar de validez y confiabilidad para la versión local del instrumento, y se espera que sirvan como base para su posterior perfeccionamiento, para ser implementado en tareas clínicas como de investigación.

La atención selectiva es una habilidad fundamental para la conducción segura. El objetivo de este trabajo fue analizar la relación entre la atención selectiva y la propensión a cometer errores atencionales en el trán sito. Treinta conductores de la ciudad de Mar del Plata (Argentina) realizaron una tarea de atención selectiva (Tarea de Búsqueda Visual Conjunta [CVST]) junto con una escala que evalúa inatención en la conducción (ARDES). Se calcularon las correlaciones de Pearson entre el ARDES y las medidas de desempeño en CVST (errores y tiempos de reacción). Se observó una relación consistente entre el desempeño en la CVST y los puntajes del ARDES. Los conductores más propensos a la inatención en la conducción cometieron mayor cantidad de errores en la identificación del estímulo objetivo (target), a la vez que presentaron tiempos de reacción más bajos. Los resultados brindan evidencias sobre el posible rol de la atención selectiva en la inatención del conductor, y muestran la utilidad potencial de una medida de búsqueda visual conjunta en el ámbito de la evaluación de conductores.

Selective attention is a fundamental ability for safe driving. The objective of this work was to analyze the relationship between selective attention and a predisposition to experience inattention errors while driving. Thirty drivers from the City of Mar del Plata, Argentina, participated in the study and completed a selective attention task (Conjunctive Visual Search Task, CVST), and a driver inattention scale (Attention-related Driving Errors Scale, ARDES). Pearson correlations were calculated between the ARDES and the CVST performance measures (errors and reaction times). A consistent relationship was observed between CVST performance and the scores reported by the ARDES. Drivers with higher driver inattention proneness tended to commit a greater number of errors in target identification while also presenting lower reaction times. The results provide evidence of the possible role of selective attention in driver inattention, and illustrate the potential usefulness of a visual search measure in the area of driving assessment.

A atenção seletiva é uma habilidade fundamental para a condução segura. O objetivo deste trabalho foi analisar a relação entre a atenção seletiva e a propensão a cometer erros atencionais no trânsito. Trinta motoristas da cidade Mar del Plata (Argentina) realizaram uma tarefa de atenção seletiva (Tarefa de Busca Visual Conjunta, Conjunctive Visual Search Task [CVST] junto com uma escala que avalia inatenção na condução (Attention-related Driving Errors Scale [ARDES]. Calcularam-se as correlações Pearson entre p ARDES e as medidas de desempenho em CVST (erros e tempos de reação). Observou-se uma relação consistente entre o desempenho na CVST e as pontuações do ARDES. Os motoristas mais propensos à inatenção na condução cometeram maior quantidade de erros na identificação do estímulo objetivo (target), ao mesmo tempo que apresentaram tempos de reação mais baixos. Os resultados dão evidências sobre o possível papel da atenção seletiva na inatenção do motorista, e mostram a utilidade potencial de uma medida de busca visual conjunta no âmbito da avaliação de motoristas.

ABSTRACT Traffic collisions involving motorcyclists are a growing problem in low and middle income countries. Helmet use is the foremost protective measure for this group of road users, however many riders do not wear them. The objective of the present study is to report the changes in helmet use during the period 2006-2014 in an Argentine city and discover associated factors for the year 2014. The sample includes more than 6,900 observations of motorcyclists carried out during the years 2006 (n=962), 2008 (n=977), 2012 (n=2,542), and 2014 (n=2,466). The data indicates a progressive increase in helmet use over time, but differences due to gender and type of rider remain. Factors associated to helmet use in motorcycle drivers during 2014 were: passenger helmet use, motorcycle type, license plate use and gender. Although the results are positive, it is necessary to be attentive to the negative consequences of the growing fleet of motorcycles.

RESUMEN Los siniestros viales que involucran a motociclistas conforman un problema creciente en los países de ingresos bajos y medios. La medida de protección por excelencia en estos usuarios viales es el casco. Sin embargo, una proporción considerable de motociclistas no lo usa. El objetivo de este trabajo es informar la evolución del uso de casco durante el periodo 2006-2014 en una ciudad de Argentina, y conocer los factores asociados durante el año 2014. La muestra incluye más de 6.900 observaciones de motociclistas, registradas en los años 2006 (n=962), 2008 (n=977), 2012 (n=2.542) y 2014 (n=2.466). Los datos indican un aumento progresivo del uso de casco a través del tiempo, aunque se sostienen las diferencias por género y función. Los factores asociados al uso de casco en conductores durante el año 2014 fueron el uso en pasajeros, el tipo de moto, la presencia de patente y el género. Aunque los resultados son positivos, conviene alertar sobre las consecuencias negativas del aumento del parque de motos.

Es creciente la evidencia de que las distracciones y la inatención del conductor constituyen un importante factor contributivo en choques y siniestros viales. El objetivo del presente trabajo es realizar una revisión de la literatura sobre inatención y distracciones durante la conducción. En primer lugar, se trabajó sobre la definición y delimitación conceptual de ambos términos; segundo, se abordaron los diferentes enfoques metodológicos utilizados para su estudio y, por último, se mencionan las medidas de intervención y de prevención recomendadas. Finalmente, se concluye que la investigación sobre el tema se enfrenta con problemas relativos a la falta de una definición consensuada de conceptos básicos, a diferencias metodológicas y a la ausencia de un marco teórico unificado que brinde coherencia a los hallazgos de investigación. Estas limitaciones en la investigación reflejan, a su vez, problemas más generales propios de la psicología del tránsito en tanto área específica de la psicología.

There is growing evidence about the riskiness of driver distraction and inattention for traffic safety. The present study is a review of the literature about inattention and distraction while driving. First, the review shows the difficulties and controversies arisen in the definition of both constructs. Second, the paper describes different methodological approaches used in the driver distraction research. Third, there is a description of prevention strategies for mitigating and avoiding the consequences of driver distraction and inattention. It is concluded that research on driver distraction and inattention faces difficulties regarding the lack of common definitions of basic constructs, the lack of a unified theoretic frame, and the presence of methodological differences. These limitations mirror problems faced in the main discipline, Traffic Psychology.

É crescente a evidência de que as distrações e a inatenção do condutor constituem um importante fator contributivo em choques e sinistros viários. O objetivo do presente trabalho foi realizar uma revisão da literatura sobre inatenção e distrações durante a condução. Em primeiro lugar, trabalha-se sobre a definição e delimitação conceitual de ambos os termos; segundo, abordam-se os diferentes enfoques metodológicos utilizados para seu estudo e, por último, mencionam-se as medidas de intervenção e de prevenção recomendadas. Finalmente, conclui-se que a pesquisa sobre o tema de enfrenta com problemas relativos à falta de uma definição consensual de conceitos básicos, a diferenças metodológicas, e à ausência de um marco teórico unificado que brinde coerência aos resultados da pesquisa. Estas limitações na pesquisa prévia refletem, ao mesmo tempo, problemas mais gerais próprios da psicologia do trânsito em tanto área específica da Psicologia.
